UK to probe Airbus's use of third-party agents to sell planes

* Airbus cooperating with UK authorities over agents' role

* Investigation likely to take years to complete

* Complicates relations with credit agencies

PARIS, Aug 8 (Reuters) - Airbus Group faces potentially lengthy disruption to its business after Britain launched a criminal investigation into suspected irregularities in the use of third-party agents to win commercial jet sales.

Europe's largest aerospace company said late on Sunday it had been notified that the UK's Serious Fraud Office had opened a formal probe after being alerted by the country's export credit agency to discrepancies relating to the disclosure of the work of local agents.

The probe raises a sensitive issue for the industry because the agency, UK Export Finance, has for years locked horns with aerospace firms about the need for more transparency, even though it does not object outright to the use of intermediaries.

Airbus Group said the SFO was looking into possible "fraud, bribery and corruption" and that the company continued to co-operate with the investigating agency, having itself tipped off UKEF about internal findings under a recent compliance drive.

"It will take years," a person familiar with the matter said of the SFO investigation, adding it was too early to predict any outcome or consequences for the company or the industry.

Airbus virtually eliminated the gap with U.S. rival Boeing in their intense battle for airliner orders in July after booking about half of the 197 firm sales unveiled at the Farnborough Airshow.

Airbus Group is already the subject of a four-year-old SFO investigation into a $3.3 billion communications deal with Saudi Arabia, while the SFO is conducting a corruption probe into engine maker Rolls-Royce which it launched in 2013.

The latest case involves discrepancies over the amount of agents' fees disclosed in applications for export support, or missing names of third parties, in some cases dating back years, people familiar with the matter have told Reuters.

In April, UKEF halted export funding over the reported discrepancies and was swiftly followed by France and Germany.

Under rules dating back to July 2006, companies applying for export support in Britain must identify any intermediaries involved in sales negotiations and list the sums paid.

The rules followed a series of policy U-turns and a fierce debate between UKEF and aerospace companies including Airbus, which had lobbied against the tougher disclosure rules on the grounds that such data was commercially sensitive and that their own codes of conduct and due diligence methods were sufficient.
